Technical Field

[0002] Most systems utilize coal-fired power plants or heat source plants to heat water to 100°C. This hot water is then pumped through large circulating pumps to the primary side of traditional heat exchange station networks, where it enters plate heat exchangers. The secondary network's water circuit exchanges heat with the primary network through a separate circuit within the plate heat exchangers. The primary network dissipates heat, while the secondary network absorbs heat, achieving the purpose of heat exchange. The heat flow direction is from the primary side to the secondary side. Monthly settlements are based on the heat / cold output meters on the primary network pipelines. Therefore, to save costs, the company strives to use the lowest possible electricity to generate more heat / cold output for users.

[0029] To enable those skilled in the art to better understand this utility model, the present utility model will now be further described in conjunction with specific embodiments.
[0030] Example 1:
[0031] like Figures 1-5 As shown, this utility model provides a cold and heat source device for a control station, including a base 7. A sound absorption and noise reduction mechanism is provided on the base 7. The sound absorption and noise reduction mechanism includes a galvanized steel plate cover 1, centrifugal glass wool 2, a plate silencer 3, and a three-way valve pipe 4. The top of the galvanized steel plate cover 1 is vertically fixedly connected to the galvanized steel plate cover 1 and the centrifugal glass wool 2. The air inlet and air outlet of the galvanized steel plate cover 1 are bolted with the plate silencer 3. The three-way valve pipe 4 is equipped with a metal corrugated compensator 5 and an elastic hanger 6.
[0032] A shock-absorbing mechanism is installed at the bottom of the base 7. The shock-absorbing mechanism includes a positioning vertical rail 80, a connecting rail 81, a sliding rail 82, a connecting plate 87, and a rubber base 100. The positioning vertical rail 80 is slidably connected to the sliding rail 82, the sliding rail 82 is slidably connected to the connecting rail 81, the outer side of the sliding rail 82 is fixedly connected to the sliding rail 83, and the sliding rail 83 is slidably connected to the sliding block 84. An air shock absorber 101 is installed between the rubber base 100 and the connecting plate 87, and a generator 9 is installed at the air outlet of the air shock absorber 101.
[0033] A cooling tower and an electric boiler are installed on the top of the base 7. Both the cooling tower and the electric boiler are connected to an external power source. The inner surface of the galvanized steel plate cover 1 is coated with a sound-absorbing layer. A cavity is formed between the galvanized steel plate cover 1 and the centrifugal glass wool 2. The centrifugal glass wool 2 is provided with perforations.
[0034] The cooling tower and electric boiler are bolted to the base 7. The control station has its own cold and heat sources. The cold source can be a water chiller or an air-cooled module. The cooling tower is part of the water chiller. The heat source can be electric auxiliary heating equipment, such as an electric boiler and an air source device.
[0035] The sound-absorbing layer on the galvanized steel sheet cover 1, such as polyurethane sound-absorbing paint, has a sound absorption coefficient ≥0.8;
[0036] Centrifugal glass wool 2 is made of perforated galvanized steel sheet with a perforation rate of 20%. The air layer formed by the galvanized steel sheet cover 1 and centrifugal glass wool 2 can form an air spring effect, which can improve the function of low-frequency noise attenuation.
[0037] Both the cooling tower and the electric boiler are equipped with metal corrugated compensators.
[0038] The operation of the chiller unit (cold source), electric boiler, and air source heat source converts electrical energy into heat and cold energy, which resides in the metal corrugated compensator 5. When users require cooling or heating, the temperature is adjusted by switching the electric regulating valves inside the station to achieve the desired cooling or heating. In this case, the temperature on the primary network side is higher than the temperature on the secondary side in heating mode, and lower in cooling mode. When user demand for cooling or heating is excessive, such as during extremely cold or hot weather, a reverse supply operation can be performed using the existing cold and heat sources. The specific operation method is as follows: by switching the three-way valve or electric regulating valve in the secondary side pipeline, the direct supply of cold and hot water from the secondary side is diverted into the plate heat exchanger. At this time, the primary network inlet valve is opened, and the supply and return water temperatures of the primary network are higher in cooling mode and lower in heating mode. The target water temperature on the secondary side will be supplied in reverse through the plate heat exchanger, exchanging the heat / cold energy.
[0039] The air inlets and outlets of the galvanized steel sheet cover 1 and centrifugal glass wool 2 are mainly used for ventilation and heat dissipation of the cooling tower and electric boiler. The cooling tower and electric boiler are not shown in the figure.
[0040] A connecting plate 87 is fixedly connected to each of the four corners of the bottom surface of the base 7. A hinge 86 is installed at each of the four corners of the bottom of the connecting plate 87. A support arm 85 is hinged to the hinge 86.
[0041] Hinges 86 are installed at the four corners of the bottom surface of the rubber base 100. Support arms 85 are hinged to the hinges 86. Both upper and lower support arms 85 are rotatably connected to the shaft. The shaft is fixedly connected to both sides of the sliding block 84. The sliding block 84 is fixedly connected to the outer walls of both sides of the sliding rail 82.
[0042] The generator 9 is installed on top of the rubber base 100. The generator 9 is connected to an external power source. The positioning vertical rail 80, connecting rail 81, sliding rail 82, sliding rail 83, sliding block 84, support arm 85, hinge 86 and connecting plate 87 are combined to form a shock-absorbing platform 8. The rubber base 100 and air shock absorber 101 are combined to form a shock-absorbing assembly 10.
[0043] Working principle: The noise generated during the operation of this utility model is absorbed by the sound-absorbing layer on the galvanized steel plate cover 1, such as polyurethane sound-absorbing paint, with a sound absorption coefficient ≥0.8. The centrifugal glass wool 2 is a perforated galvanized plate with a perforation rate of 20%. The air layer formed by the galvanized steel plate cover 1 and the centrifugal glass wool 2 can form an air spring effect, which can enhance the function of low-frequency noise attenuation.
[0044] The plate silencer 3 can absorb the noise transmitted from the air inlet and outlet of the galvanized steel plate cover 1. The metal corrugated compensator 5 is used at the connection of the three-way valve pipe 4 to reduce vibration transmission. The metal corrugated compensator 5 is installed on the three-way valve pipe 4 to provide elastic support and absorb vibration energy.
[0045] The sound absorption and noise reduction mechanism, through the integrated application of galvanized steel plate cover 1, centrifugal glass wool 2, sheet silencer 3, metal corrugated compensator 5 and elastic hanger 6, forms a multi-level noise reduction and vibration reduction system. The closed structure forms a physical sound insulation layer, which effectively blocks the mid-to-high frequency noise directly radiated by cold and heat source equipment and reduces the outward propagation of sound energy.
[0046] During the process of the air shock absorber 101 being raised or lowered, the connecting plate 87 is raised or lowered synchronously.
[0047] The downward movement of the connecting plate 87 causes the connecting rail 81 to slide vertically in the sliding rail 82, and the sliding rail 82 to slide vertically in the positioning vertical rail 80. The downward movement of the sliding rail 82 causes the sliding rail 83 to descend synchronously. The descent of the sliding rail 83 causes the sliding blocks 84 on both sides to slide away from the sliding rail 82. The sliding blocks 84 also slide along the horizontal direction of the sliding rail 83. Through the setting of the shock-absorbing platform 8, when eccentric vibration occurs due to load changes such as compressor start-up and shutdown, the expansion structures on both sides can provide additional lateral support to reduce equipment tilting. The sliding structure can absorb lateral impact force and protect the body of the shock-absorbing component 10.
[0048] During operation, the vibration damping component 10 will generate mechanical vibration due to the reciprocating motion of compressed air. The generator 9 can convert the vibration energy into electrical energy through the piezoelectric effect or electromagnetic induction principle, thereby achieving the advantages of energy recovery and energy consumption reduction.
[0049] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
